I made one from Scratch too, using an Idea from the time that i've done an mod that added 20% health more on Grinder If you have the time i Will place It here, showing It , i can sendo tô you in another way, and i Will try again this night

But basically what i did in the mod that i did yesterday It
I changed upgrades to 3.2 "weapons_passive...

It haves weapons_passive_swap speed 1 ( rougue uses It, and 2 that i dindnt find anything that used It.

It dindnt change rougue, and the Hook was the same used in a mod , that as i said on top, that added life in Grinder

I tried to add more skills, like the passives swaps, life, Dodge, armor, health. But none did work

skills.lua, (dont mind the numbers, i was testing to feel diference.... but nothing) first one is rougue(values.weapon.passive_swap_speed_multiplier_1) second one is values.weapon.passive_swap_speed_multiplier_2

local data = UpgradesTweakData._init_pd2_values
function UpgradesTweakData:_init_pd2_values()
data(self, tweak_data)

--Copycat--
    self.values.weapon.passive_swap_speed_multiplier = {
	12.2,
	3.2
	}
}

end

tree.lua

local skill_data = SkillTreeTweakData.init

function SkillTreeTweakData:init(tweak_data)
skill_data(self, tweak_data)

@ashdavis The problem with your copycat edit is that you're editing your own local variables, not the perk deck data that's in the game. The perk deck definitions are in self.specializations in skilltreetweakdata. You need to access and edit those- those, you can set to a local variable for easy access, because of how tables work in Lua.
eg. (assuming this is inside the SkillTreeTweakData.init hook)

local crewchief_deck = self.specializations[1] -- get the first perk deck
local card3 = crewchief_deck[3] -- get the third card from that deck
for i=#card3.upgrades,1,-1 do -- instead of using pairs or ipairs, iterate through the upgrades array backwards (largest to smallest)
    -- so that removing upgrades doesn't disrupt the iteration order

	table.remove(card3.upgrades,i) -- remove the upgrade in this iteration; repeats through the whole list, so all upgrades will be removed
end

removes all the upgrades from the third card of Crew Chief (the first perk deck)

@offyerrocker
Kay thanks!!!

but it should at least had the extra effect in placed, no?

@ashdavis Your code wasn't doing anything to the game because you pointed it to a new table that you made- it was copied from the game, but it has no link to the game's code.

You had a line that said: table.insert(mrwi_specialization[1].upgrades, "weapon_mrwi_secondary_reload_swap_primary_1")
but mrwi_specialization[1] is a local variable that you declared yourself. If you want to edit the perk deck in the game, you need to point it to the perk deck in the game.

Is that what you mean?
